To celebrate Science Week, the RTÉ Weather team are sharing some fun facts about - you guessed it - the weather! In the video above, Nuala Carey explains everything we need to know about atmospheric pressure. 

We've all made vague, unknowing references to the "pressure" of a day or days feeling "heavy", and we know that atmospheric pressure plays a huge role in weather. The problem is, many of us don't know what that role is exactly. 

According to Nuala, high pressure is linked to "settled, dry weather" and, though we might not notice it, the wind around these areas moves in a clockwise motion. 

It makes sense, then, that low pressure is tied to unsettled conditions, high winds, and air moving in an anticlockwise fashion. Low pressure also causes air to moves upwards, forming clouds which eventually release moisture in the form of rain.
